I'm wondering how suited the sd API is for general metadata lookup, not in conjunction with an EPG, i.e., for any TV show ever aired, not just those showing now or scheduled for broadcast. For example: Gunsmoke, Bewitched, I Love Lucy, Friends, Limitless.

Looking briefly at the API documentation, it appears one has to have a "programId" to do a metadata retrieval. I didn't see an API function for obtaining the programId for a given episode of a given series, or for getting a list of all programId's for an entire series along with episode titles for each episode, or something similar.
